The foregoing construction is old, so for this invention is concerned, and will be ioun d more fully and clearly described in the reissue application of Frank P. Dunn, Sci". no. 392,078, Sept. 9, 1907.

My invention consists in adding to the foregoing construction or to any other scsle construction, means substantially as hereinafter described.

Thelever 12 at its inner end has an arm with trensversely extending pin 31 projecting thcrethrough, as shown in Fig. 2. Y detacheble poise 37 is rovided with a pair of upwardly extending nooks 84 that are adepted to be cen ht upon the pin 31 and, when the inner en of the lover is elevated by the loud, to lift said poise so that said poise can set es on additional counterevcight to the, load. The detachable poise 37 is supported by a plate 38 u on which it rests. This plate has on upwer ly projecting cone 35 nndtho poise 37 has in the bottom thereof it conical recess so that the poise surrounds and fits upon said cone 35 end the cone centers and holds the poise in position when it being deposited upon the plate 38. The top of the base 10 is apertured at All for the verticsl movement oi the poise 37, and the plate 38 is mounted below the top 40 within the base 10 and hes en upwardly ending hooked finger or flange 42 at its left hand end 1 opening 41 so that, 38 is in its lowermost positop 40 of when the plate tron the fin ers 42 will on o e the 1 is ls s the base and support the rear end oi the plate 38 while in its nornnil position. The plate 38 at its right-hand end has :i pinto "l4 projecting therefrom vertically and to the, right, shown in Fig. 3, that has an inclined slot 45 through which the pin 46 from. the '1 front wall of the base and bracket l ll'i prol jocts, so that when tiieplstc ll is moved mtl orally the plate 138 endpoise 37 will be moved not only laterally but also vertidully. 'ifhcl lateral movement of the pistes 3S and L4. is caused by a com disk 50 ri idly mounted on a shaft 51 that projects t irough the front well of the base and the bracket 15l and on its outer end has am nctnzit ing lo VOl 52 secured thereto, whereby sold cam disk 50 earn be os- Said com disk provided with n. l coin groove 53, as shown in Figs. '6 and 7 and 5 into said groove 53 it pin 54 'l'i'oin. the plate 44 ,1 projects. Therefore, when the coin. disk 50 is oscillated from the position shown in Fig. (i l to the position shown in Fig. 7 by throwing the lever 52, from the dotted shown in Fig. 1 to the full line line position l position. the

lever 12 is elevated M will be drawn lei-ereily from the posi have in 'liig. 6 i. shown in Fig. '7 and, 1(118'501'6, the plot 5 the right and upward-{, rain the position shown in Fl into the .llOll shown in Fig. 4. The iii-st described riu -vcinent discn gages the poise 37 from the s. .r, shown in Fig. 4;, and permits the operation of the scale, as it said additional poise 37 were not present. When, however, it is desired to increase the capacity oi the scale, to the extent oi the poise 37, the er is a r ved from the full line position shown in Fig. i to the dotted line position and that returns the cam disk from the position shown in Fig. 7 to that shown in Fig. 6 which moves the phttes 3S and 44 laterally from the position in Fig. to th it shown in 3, and us the poise moves luterellynnd downwsrdly the hooks 34 move over and upon the pins Stops 53 are provided on out 'he H) for the end oi the lever 52 t.

pin r. lrlOZ ri l r ie end drevni. to J! Sometimes the person operltting i 'e not move the lever and therefore the plate 31% end poise 3.7 to their limit move ment. To avoid this (irtiicuity and automatically move said ports to their limit of movement, I. provide the following mocha-nisin. A lateral and horizontal sliding bar is provided within the base 10 with the left hand endiorked so as to ride upon and he held in piece and guided by the shaft 51 The other end has-e hook. in that rides upon a pin 62 troi. the bracket which extends down from the top 40 of the base 10. [it the left hand end of said her ('50 there is on inwrtrdl extending pin 64 that projects into the corn groove 53 of the coin. disk, as shown in Figs. 6 and 7. Consequently, AS the cam disk is operated, said bar 60 will be reciproceted, but it the coin disk is not completely operated the loiig itndinel movement of the her 60 to the left will complete sold oveinent oi the disk.

Vv lll V her ()0 to the hit. flhis completes the 0501]- lotion oi the disk 50 because if said \disk is left in onlincoinpletel'y operated position, see Fig. 8, whether you are moving the lever 52 in one direction or the other, the inclined portions of the groove 53 in the disk 50 are so arranged that the pushing of the pin 64 to the left will ceuse the disk to finish its incomplete osci lntion. Thus in ll) such movement to the left oi the pin 64. will cause the disk to move in the direction of the arrow until it has reached the position shown in Fig. 7 and it will force the disk in the direction of tie arrow in Fig. 11 so as to bring the disk in.- t e position s llown in 'Fig. 6.

A check bar 100 of well knowlrconstrud. ti'on extends from'thc load receiving member int'e theorising where its inner end is pivoted, for leveling the scale pan. Said check bar consists of along portion secured at its outerv end rigidly to the load receiving member 13, and its inner end is "turned up and projects in't'othe 'h'ousin and is pivoted to a short ier that is pivoted to the housing, -the same not bein shown in ,full lines, 'bfltby'dotted lines in ig. 1, and being substantially the same in character as the check shown in Letters Patent granted toBenjamin DrEmanuel, Nov. 1v, 190s,-904,251.

What I claim as m invention and desire to secure by Letters at-ent is:

1. The combination with the lever of a scale, of a poise ]provided with a hook adapted to enga 0 said e ver and means independent of said ever for moving said poise at an inclination to a horizontal line whereby when it is elevated the hook thereon will be out of the path of movement of the lever and when lowered will engage said lever.

10. The combination with the lever of a scale, of a detachable poise, mechanical means for connecting said poise with said lever or disconnecting the same as desired, and means actuated by the lever for moving said poise-placing means to its limit of moved.

.11. The combination with the lever of a scale, of a detachable poise, means 0 erable by the operator'for connecting sai poise with and disconnecting it from said lever, and means controlled by the lever for completing the movement ofsaid oise-placing means when it has been partially moved.

12. The combination with the lever of a scale, of a detachablepoise, a movable plate on which said poise rests when not elevated therefrom by said lever, means for the movements of said plate at an inclination to a horizontal line, an oscillatory cam for movin said plate, means for the operator to osc ate said cam, and means actuated by the o "ration of the scale lever for comp etin t e movement of said cam when the same as been artially moved.

13. The com ination with the lever of a scale, of a detachable poise, a movable plate on which said poise rests when not elevated therefrom by said lever means for the movements'of said to a horizontal line,

uiding said arm will actuate said bar and cause it to com lete the movement 01 said cam.

14. he combination with the lever of a l scale, of a detachable poise, a movable plate upon which said poise rests, there being a part projecting from said plate in which there is an inclined slot, a pin mounted stationary in the scale that projects through said slot, a cam means for the 0 erator to oscillate said cam, a pin from sai cam plate entering the groove in the cam,

whereby Said Weight may be mechanically connected with or is- 1 connected from said lover, a longitudinally movable bar, a pin from said bar projecting i into the groove in the cam, and an arm projectin from the scale lever for actuating 1 said bar when the lever is tilted by a load, the groove in the cam being formed substantially as shown so that said actuation of the movable bar will move the cam and cause the poise to be moved to its complete limit of movement in either direction.

In witness whereof, I have hereunto afiixed my signature in the presence of the witnesses herein named.
